Explanation:
Maybe you could comment here the choices if it's multiple choice.
Answer
The velocity of the bird is 2 m /sec .
Explanation:
The formula for kinetic energy is given by.
Where m is mass , v is the velocity .
As given
A 4.0 kg bird has 8.0 joules of kinetic energy .
m = 4.0 kg
K.E = 8.0 joules
Putting in the formula
Thus
v = 2 m/sec
Therefore the velocity of the bird is 2 m /sec .
Answer:
Yes
Explanation:
A body can possess velocity at the same time in horizontal and vertical direction
For example
A projectile
In electricity, the most famous and basic equation is the Ohm's Law which relates the parameters voltage, current and resistance. One form of this law as written in equation is V = IR, where V is the voltage in volts, I is the current in amperes and R is the resistance in ohms. These parameters depends in the arrangements, whether it's series or parallel.
In a series connection, the voltage is greater across a high-resistance resistor. Therefore, the voltage is much greater for the 20-ohm resistor. However,if it is a parallel circuit, the voltage is just the same for both resistors.
Answer:
False
Explanation:
Solid water (ice) has a lesser density than liquid water. Hence, the statement is false.
